HAYRACK CLAMP.

Specification of Letters Patent.

Application filed November 2, 1914. Serial No. 869,858.

To '17? whom it may concern lle it known that I, Ivnn H. Len, a citizen of the l nited States, residing at ,Viborg, in the county of Turner. State of South Dakota. have invented certain new and useful Improvements in Haydtack Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to clamps, particularly to clamps for securing a hay rack, and has for its object the provision of a clamp whereby a hay rack may be secured without the necessity for boring holes in the rac thereby weakening the same.

An important object is the provision of a clamp which will be quickly and easily attached and detached, which will be secure and fast in its action, durable in service and a general inmrovement of the art.

With these and other objects and advancages in view the invention consists in the novel construction and arrangement of parts as will be hereinafter more fully described and claimed and illustrated in the accompanying drawing, in which- Figure 1 is a perspective view of my novel clamp applied to a hay rack and in its unlocked position. Fig. 2 is a view looking at a cross bar of the rack showing my clamp in its locked position. F 3 is a similar view looking at the face of the side bar, and Fig. 4 is a detail horizontal sectional view.

liiei erring more particularly to the drawing the numeral 5 designates a bed piece of, my rack and (3 designates a cross bar on the bed piece 5.

in order that the cross bar 6 may be clamped upon the bed piece 51 provide an upright member 8 formed asa rod having an oli set portion 9 adjacent its lower end and terminating in a hook 1O engageable beneath the bed piece The upper end of the rod 8 is screwl'hreaded. shown at 11 for the reception of a out 152'. A second rod 13 is adapted to coact with the rod 8 and compi a straight port-ion l lbent intermediate its ends to form. a loop 15, terminating at its lower end in a loop 16, the loops 15 and 16 being disposed upon the upright inember S. The rod 13 terminates at its 'upper end in a loop 17 which is engaged by a movable clamping memberto be described- The i'novable clamping member comprises a straight bar 18 provided at one end with a loop 1! engaging the loop 17, bent at rlght angles as shownat 20 and ad1acent the loop 15) amlterminating at its other end in a retlcxly bent loop 21. A ring 22 is disposed slidably upon the rod 13 for a purpose. to he described.

My device is used as follows: The rod 13 is positioned against the sideof the cross bar (3, with the hook lO'engaging the lower side of the bed piece The rod 13 is then disposed in relation to the rodS with the loops 15 and 16 engaging upon the rod 8, from which they will be prevented from removal by the nut 12. The locking rod 18 is then swung over the cross bar 6 and swung down- \vardly until the hook 21 is adjacent the rod 13. The ring is then slid over the book 21. to hold the rod 18 against outward and 4 Patented July. (5, 1915.

upward movement, thereby clamping the cross bar 6 firmly and securely upon the bed piece 5. In order to release the clamp it is merely necessary to move the ring 22 upwardly until it disengages the hook 21 whereby the rod 18 can be moved upwardly out of engagement with the cross bar 6. If it should be desired to adjust the rod 13 relatively to the bed pieces 5 in order to clamp larger or smaller cross bars, such may be readily accomplished by rotating the nut 12 in the proper direction. to raise or lower said rod on the upright. member 8. It is to be noted that when applied the nut 12 has one of its tlat faces bearing against the bed piece 5, the nut being in this manner held against rotation and accidental displacement of the parts prevented.

From the foregoing description and a study of the drawing, it will be apparent that I have thus provided a novel and simple hay rack clamp which will be easy to attach, and detach, positive and secure in its action, and not likely to get out of order.

It will be readily understood that i reserve the right to make various changes in the form, construction and arrangement of parts withoutdeparting from the spirit of the invention or limiting the scope of the subjoined claims.

Having thus described my inventioml clai.m
